Patented Feb. 1s, 1930 UNITED STATES PATENT OFFICE HIRAI N. BERRY, OFGREENVILLE, MISSISSIPPI, ASSIGNOR, BY DIRECT -AND' MESNE ASSIGNMENTS, TOCOTTON HARVESTER CORPORATION 0F AMERICA, OF WILHING TON, DELAWARE, ACORPORATION OF DELAWARE COTTON PICKER Original application led April 23,1927, Serial No. 186,148. Divided and this application iled February 9,

1928. Serial My present invention relates to that type of cotton pickeremploying rotating spindles radiating from revolving drums or cylindersand having stripper bars in series around the cylinders, which bars areshiftable inwardly and outwardly along the spindles, and is moreparticularly a division of my copending application, Serial Number186,148 describing and claiming means by whit-h the stripper bars are soconnected as to present substantially an unbroken wall in order to avoidany danger of cotton iinding its way around the stripper bars andpacking upon those porions of the spindles inwardly beyond the ars.

My present application is limited to that form of construction outlinedin my above application wherein the connections between the bars are inthe nature of jointed plates adapted to flex at and between the bars toavoid any interference with their movements for the purpose set forth.

In the accompanying drawing, which illustrates my present invention andforms a part of this specification,

Figure 1 is a partial horizontal section through a cylinder showing theapplication of my improved connecting plates between the stripper bars,and,

Figure 2 is a detail perspective view, on an enlarged scale, of a pairof stripper bars and 'their connecting plates.

Referring now to Figure 1, I have shown at 10, a picking cylinder usedin practice substantially as shown in my copending application 8,134filed January 14, 1926. The picking of cotton is accomplished by aplurality ot' picking spindles 11, radiating from the cylinder 10, androtating upon their own axes during revolution with the cylinder. Thecotton wraps around the spindles at one side ot v the cylinder and as itrevolves the tufts of cotton are gradually pushed outwardly along thespindles by means of stripper bars 12, one for each vertical row ofspindles. These stripper bars revolve with the cylinder and in suchmovement are guided inwardly and outwardly by stationary guides 13,eccentric with respect to the cylinder so that at a point rapproximatelydiametrically opposite to the first mentioned side of the cylinder thetufts ot' cotton are pushed to the extreme ends of the spindles and maybe easily and effectively removed by a simple dofiing mechanism, suchfor instance as that shown, in my application 8,134 above mentioned.

Since it is possible cotton might find its way around the stripper barsand become packed upon the spindles inwardly beyond. the bars, I proposeto connect the latter by means of hinged plates 14, and 15, arranged inpairs between successive bars throughout the series. The plates of eachpair are hingedly connected to one another at their inner adjacent edgesand are similarly connected at their outer edges to the stripper bars.It is thus possible to make the plates of counter-part construction andto employ hinge pins or pintles 16, capable of ready,

easy removal in order to promote quick access to the cylinder in caseadjustment, repair or substitution of parts becomes necessary. Theflexing of these plates on their hinges avoids any interference with thedesired operation and functions of the stripper bars and still permitsthe plates to form with the stripper bars a substantially unbroken wallaround the cylinder, effectively preventing the passage of cottoninwardly beyond the stripper bars.

Having thus fully described my invention, what I claim is,

1. In a cotton picker including a picking cylinder, peripherallyoutstanding picking spindles and stripper bars revolving with thecylinder and operating lengthwise of the spindles, means consisting ofhin ed plates connected to the stripper bars andI forming therewith asubstantially unbroken wall for protective purposes around the cylinder.

2. In a cotton picker, including a picking cylinder, peripherallyoutstanding picking spindles, and stripper bars revolving with thecylinder and operating lengthwise of the spindles, means consisting ofhinged plates connected to the stripper bars and forming therewith aprotective wall around the cylinder, said plates having quick detachableconnections permitting ready access to the cylinder.

3. A cotton picker including a picking c linder, radially outstandingpicking spin les carried b and revolving w1th the cylinder, stripper arsrevolvingl with the cylinder and operating .along t e spindles, andlates arranged in pairs between the several ars, the plates of each pairbein hingedly connected to one another along t eir inner edges andsimilarly connected at their outer edges to the strip er bars.

4. A. cotton plc er including a picking c linder, radially outstanding1cking spind es carried by and revolving,I with the cylinder, stripperbars revolving with the cylinder and o erating along the spindles, andplates ilexib y connected to one another and to said bars, and formingwith the lattera substantially unbroken wall around the cylinder forthe' purpose set forth.

In testimony whereof I aix my signature.
